Modern imaging techniques have great importance in the diagnosis and therapy of skull-base pathologies. Many of these lesions, especially in relation to their specific location, can be evaluated using CT and MR imaging. Tumors commonly found in the anterior skull base include carcinoma, rhabdomyosarcoma, esthesioneuroblastoma and meningioma. In the central cranial fossa, nasopharyngeal carcinoma, metastases, meningioma, pituitary adenoma and neurinoma have to be considered. The most common neoplasms of the posterior skull base, including the CP angle, are neurinoma, meningioma, nasopharyngeal carcinoma, chordoma and paraganglioma. One major task of imaging is the evaluation of the exact tumor extent as well as its relationship to the neighboring neurovascular structures. The purpose of this review is to recapitulate the most important anatomical landmarks of the skull base. The typical imaging findings of the most common tumors involving the skull base are also presented.
现代成像技术在颅底病变的诊断和治疗中具有重要意义。这些病变中的许多，尤其是考虑到其特定位置时，可通过CT和磁共振成像（MR）进行评估。前颅底常见的肿瘤包括癌、横纹肌肉瘤、嗅神经母细胞瘤和脑膜瘤。在颅中窝，必须考虑鼻咽癌、转移瘤、脑膜瘤、垂体腺瘤和神经鞘瘤。后颅底最常见的肿瘤，包括小脑脑桥角，是神经鞘瘤、脑膜瘤、鼻咽癌、脊索瘤和副神经节瘤。成像的一项主要任务是评估肿瘤的确切范围及其与相邻神经血管结构的关系。本综述的目的是概括颅底最重要的解剖标志。还介绍了累及颅底的最常见肿瘤的典型成像表现。
